+# Ev3
+
+To start your Phoenix app:
+
+  1. Install dependencies with `mix deps.get`
+  2. Create and migrate your database with `mix ecto.create && mix ecto.migrate`
+  3. Start Phoenix endpoint with `mix phoenix.server`
+
+Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
+
+Ready to run in production? Please [check our deployment guides](http://www.phoenixframework.org/docs/deployment).

+# ever sent via http, always redirecting to https:
